Be it known that we, GEORGE H. T. Sonna- Nnn and SYLVAIN I-I. SSsKrND, citizens ot the United States, and residents of the city` description of the same. n

This invention relates lparticularly to the mixing and dispensingof` ,carbonated beverages liavored with syrups.

Among the objects of the invention is to provide a combination and arrangement or parts in a faucet, whereby an accurately predetermined quantity of lavoring syrup may f be mixed with a flowing stream of ycarbonated or other liquid or liquids before liberation from the faucet at atmospheric pres-k sure. A further object is to preserve the sharp fizzy quality of such drinks, resulting from the process of blending and thoroughly mixing the constituents of the beverage, by the atomizing elect of delivering the constituents from a single outlet under high pressure, by the expansion due to liberation into atmospheric pressure, other objects and advantages will appear as this description progresses. In the followingr description soda water. will be understood to include any charged waters.

The generally accepted practice in this art is to measure a quantity of lavoring syrup into a glass, then inject into the glass, at low velocity, a quantity of carbonatedl water, then to project at high velocity a further 'quantity ot the samecarbonated water in- 0 tended to stir and mix the contents ofthe glass into a foaming beverage. Itis a tact, however, that that method does not thoroughly mix. the syrup and the soda water and before the beverage is consumed the syrup will settle, leaving a too sweet stratum at the bottom '0I' the glass. A further disadvantage of this old method is thatvthe stirring eiiect, to'accomplish even a poor mixing ot the contents, `liberates the carbonio acid or other gas from the soda water in great volume before the drink can be served. resulting in the beverage becoming flat before it is entirely consumed.

and all artificial or naturally Y By our apparatus the syrup and the soda water areintimately mixed and blended, while the soda water is still under pressure,

preventingfthe liberation of the gas'therein.

The mixture flowing into the serving glass in acoarse stream is so well mixed that it will not stratify in the glass, therefore requiring but little injection of the line stream to form the'desirable foam or .,head on the beverage, that is thus served to the customer directly from the faucet in the minimum of time, with the iiavoring thoroughly dissAn raaivorsco, CALIFORNIA, A-'coaronntributed in suspension and the gaseous content retained to the maximum extent; thus saving time in dispensing while maintaining the high quality of thebeve'rage. In addition tothe above .mixture, city water. grape ljuice, ginger ale ory any other liquid may be added to the beverage through the same nozzle, at the same time.

In this specification and the annexed drawings, the invention is illustrated inthe form, considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms; and it is also to be understood that in and by the claims following the description, it is desired to ycover the invention in whatsoever form Q it mayV be embodied. f

In detail the construction illustrated in the drawings, includes a suitable fountain 1 into which the neck Bof the faucet is attached. rilhe syrup pump consists of a cylinder vattached to an open end of the neck 2. rllhis cylinder is `finished to receive the pistonv 4, having a piston rod 5 eXtending forward coaxially with the nec r The head of the cylinder 3 is provided with the inlet 6 connecting with the by-pass 7 that is connected with the syrup conduit S leading to a reservoir, not shown. The cheek valve 9 is interposed .in the inlet 6 to prevent the syrup being forced back into the reservoir by the returnstroke ot the pump, this valve 9 opens on the suction stroke only. The valve 9 is held normally closed The outlet from the pump is closed by the check valve 12 seated by the spring 13. The elbow 14 is attached by the couplings 15 to the outlet of the syrup pump and is connected with the syrup conduit 16 that connects with the port 17 in the stationary block or plug 1S. This block or plug 1S is preferably of block tin, having the various passages drilled thereinto as will hereinafter --be more fully described. The port 17 leads to the passage 19 drilled transversely into the block 18 to meet the longitudinal passage 20. rllhe passages 19 and 2O meet the vertical passage Q1 drilled upward through the nozzle The passages 19, 2O and 21 t'orm a Y with the stem J1k at right angles to the Vpassage 20. The i her iinaifter referred to will be understood'to includethe three passages 19, 2O and 21.

The neck Q supports the transverse head or casing 25%, the cover 24er' which is removably attached, to permit access to Vthe 4valve mechanism within. Referring topliig. 1, the block or plug 18 is secured within the casing by the lugs by the screws Y rlhe neck 22 protrudes through the bottom olI the head and is threaded to receive the nipple 27. The end of the block 18 is threaded as at 28 to receive the cap 29 that bears against the shoulder' jl. rlie end or' the block is centrally bored to receive the iiasher preferably ot leather, rubber compound or other semi-resilient substance suitable for the purpose, see F 8. The metaldistributing disc 33 bears agi-inst the plane ot the Vwasher r)The distributing disc `is ysetLwithin the cup having the transversev lug 35 and the trunnion thereon, the latter projecting into the central hole 3i' inthe coupling 38 that is transversely grooved as 'it 1:59 to receive the lng 85. The sliaift 40 the conf pling projects throi the centralliole in the cap 29. The discs i315 and 323 co-operate to form a iace jvalve. rllhe disc 3:2 is provided with the central opening 41 bored into the axis of the block 18 to coincide with the passage 42, drilled thercinto to meet the transverse passage 13, that is connected with the conduitlcs ling te the source et soda water supply. The disc V33 is provided with a return passage in co-axial alignment with the passage 41 having the outlet 45 that is adapted to be swung into registry with the ports 4G, and 4S through the washer and arranged in concentric relation Vto the axial opening 41. rEhe port 48 is adapted lo communicate with the passage Q0 during the discharge stroke ot the syrup pump. For this reason the port 48 is elongated in proportion to the stroke ot the pump. The distributing passage 45 is adapted to be brought into registry with the ports 46, 47 and 48 in the washer that are registered with the passages 48', 49 and 2O drilled into the block 18, whereby the soda water admitted through the axial supply passage may be distribi/t ed, at the 'will oit the operator, through nozzles 52, and 51; 51 being a combination ot soda and syrup. be'l g a coarse flushing stream of soda; 53 being a jet for high velocity ot soda water. To break up the force ot the flush stream l provide the end of the nor/.ele 52 with perfo-rated ca p The end of the block 18 has the extension 5 screwed thcreinto and extending through the end 56 oit the head 23. The sleeve l" is oscillatahle upon the stem cytension and in the end 5G ot the head This sleeve is provided with the crank arm 5S. piroted at 59 to the link (il, that is pivotcd at 62 to the end et the piston rod .Slot the syrup pump. City weten is led into the block 1S through the supply pipe 63 into the chanil'aer 64,' controlled by the Valve Gli controlling the outlet passage GG that leads to the nozzle (S7 within the nipple Q7. rllhe faire 65 is controlled by the stem G8 seated by the expansion oi: the spring G9, contained within the stein and expanding against the linger pressure knob 71. Y

',l`he combination handle has the convenient knob 72. lfrom which the side extensions 73 and 74eXtend symmetrically downward llO guided in the hub to the end of the bell crank lever 85, fulto their respective hubs and 76. The hub 75 encloses the annular enlargement 77 on the end of the' sleeve 57, that is provided with'a transverse detent yor hole to receive the latch 78. see Fig. 13, guidedv in the hub 75 that isiulcrumed on the pin .78 in the handle 73. The upper end ot theA lever flares outwardlv to form the oiri 79 ad-` .Y a a jacent to the knobV 72, adaptedy to be'y depressed by the thumb of the operator inward to litt the latch 78 out-of engagement with the head. 77. The collar 80 engages the stub 4() of :the soda valve coupling and is enclosed within the -hub- 76. The hubs 75 and 76 are held in l`position respectively by the bushing 81 threaded in the stem 55, and by the nut 82 threaded on the end of the stub 40. The collar 80 is provided with a lateral hole or recess to receive the plunger 76 and pivoted at 84 crumed at 86 and having" the grip 87 exposed beyond the handle 74. This plunger 88-is held normally seated in the collar 8O bythe expansion of the spring 88; a similar construction being repeated in the handle 73 with respect to the plunger 78'. 56 oi1 thehead is provided with a gauge 89, interposed betweenythe hub 75 and the end 56 and havingthe lateral lug 90 thereon extending int-othe path of the handle 73. For the purpose of adjusting the radial position ot this'lug 90, the gauge 89 is provided with the slot 91 engaging the set screw 92, threaded in the end 56 by which the stroke of the handle.73 may be regulated to measure the vquantity of syrup ejected by the pump 3. The conduits i-fl and 68 being of block tin tubing ot easily bendable nature, I provide the two clamping bars 93 and 9e on the return elbows 14, having the screws 95 threaded therein and adapted to be. screwed against the conduits ill and 68, to hold them from rotation while they are 'being coupled to their respective sources oir' supply ot carbonated water and city water.

This invention operates substantially as follows: lh en the operator pulls the handle 7 2 forward, it rotates the sleeve 5.7, causing forward movement of the crank 58, that in turn pullsthe piston et of the syrup pump forward sucking syrup from the syrup supply into the pump 3 'past the check valve 9. Qhe handle 72 is then torced back, see Fig.` 2, to the dotted line A. limited hy the position off the lug 90. rlhis forces the piston i backward forcing the syrup out .of the pump 3 pastfthe check valve l2 through the passage 19, see Fig. 16, and' through the passage 2l to the nozzle 5l. Simultaneously with the stroke ot the pump thedistributing disc takes n. supply ot' carbon'atingwater under pressure through the passages 42, 4l and l5; and port 46 to passage 20, and

-ated'water to mix discharged through the nozzle 5l' into the The end draw the carbonated brings the soda water to the outlet through the passage l2l to the nozzle 5l simultaneously with the syrup discharged therethrough, causing the syrup and the carbonbefore the beverage is drinking glass for serving. Immediately the handle 73 contacts with the lug 90 the handle is reversed and moved forward to the neutral position llig. 2, then the grip 79 is pressed releasing the latch 78 as the handle 72 .is moved forward to the second dot-ted line Bf which connects the port stl through the distributing washer 32 with the port .7 in washer 32 and with the passage 4:8 connecting with the flush nozzle 54,

initting caibonatedwvater to tlow'- into-the serving glass "to the desired extent. u The handle 72 is then moved forward to the Erst dotted line C which permits the carbonated water under pressure to pass through the passage 48 connecting with the iet nozzle 53, which projects a jet of carbonated water into the serving glass at high velocity7 serving to thoroughly mix the conteutsand to create thereon the vnecessary `foam or head `The forward movement of n the handle 72 to neutral, Fig. 2, has moved the-pump piston lforward lilling the pump 3 with syrup ready for a second serving as described. lVhcn the handle V72 is moved baclto the perpendicular position, illustrated in Fig. 2. all of the vvarious passages through the soda control valve are closed and the pump 3 being charged with syrup ready tor succeeding operations as described.

AIt it is desired to add a little more syrup to the glass olbeverage already drawn. the finger grip 87 is pressed releasing the plunger 83 from the soda valve control 80. permitting the rpump 3 to be operated to any desired extent for the purpose ot ejecting syrup. ontrawise if it is desired to water through either of the nozzles 53 or 54C the finger grip 79 is pressed inward releasing the plunger 78 from engagement with the sleeve 57 disconnecting the syrup pump and permitting tree manipulation of the carbonated water valve to the extent desired. f .i

Ifit ris desired to draw aglass of city water or to dilute the contents of a glass of beverage, pressure on theexposed linger press head 71 opens the water valve 65, permitting water to How through the nozzle 67.' It is obvious that ginger ale or ani,7V other form ot through this water valve instead ot. water. While this faucet was designed primarily for the blending and mixing ot kroot-beer syrup with carbonated water, it is obvious Y rthat any forni ofsyru and blended in combination with the carbonated water and diluted with city water or any other syrupor beverage under conp may be thus served beverage may be served `ith said faucet, hay/ing soda water; and
